Answers
Answer:
There are 20 items on one grocery list and 13 items on second grocery list.
Step-by-step explanation:
We are given that there are two grocery list and one of the grocery list have seven things less than the other grocery list.
Let x be the number of items on one grocery list.
Then, by the given information, there are x -7 items on the second grocery list.
The total number of items on both the list are 33.
Then, according to the question,
Thus, there are 20 items on one grocery list and (20 -7) = 13 items on second grocery list.
2x+7=33
2x=26
x=13
x+7=20
13+20=33
one list has 13 items, the other list has 20 items

Since the squarebase has side 6 cm and triangular side has height 10 cm, the total surface area of square pyramid is 156 cm²
What is the Total surface area of a square pyramid?
A square pyramid has a square base and four triangular sides, its surface area, A = area of square base + 4 × Area of triangular side.
Area of square base
Area of square with side, L is A = L²
Area of triangularbase
Area of triangle with height and base, L which is the length of the square base is A' = 1/2Lh
Thus, total surface area of square pyramid ,
A" = L² + 4 × 1/2Lh
= L² + 2Lh
Given that the length of the square base is 6 cm and the height of the triangular side is 10 cm.
Now substituting the values of the variables intot he equation, we have
A" = L² + 2Lh
A" = (6 cm)² + 2 × 6 cm × 10 cm
A" = 36 cm² + 120 cm²
A" = 156 cm²
So, the total surface area of square pyramid is 156 cm²
